AC 9535
And thou shalt make a border of gold to the closure thereof round about.
That this signifies the bounding of the sphere of Divine good,
is evident from the signification of "a border of gold,"
as being the fixing of the bounds by the Divine good;
and from the signification of "the closure thereof,"
as being conjunction with truth from the Divine.

AC 9536
And thou shalt make for it four rings of gold.
That this signifies the ultimate receptacle of the heavenly marriage,
which is that of Divine good with Divine truth,
is evident from the signification of the "four rings of gold,"
as being Divine truth conjoined with Divine good everywhere round about,
thus the ultimate receptacle of the heavenly marriage,
which is that of Divine good with Divine truth.
